For summer, Our son will be entering 7th grade next year. The plan was to have him take the course challenges starting with 4th grade as a way of identifying gaps. 4th grade was an arbitrary choice but I reasoned he has probably missed a little each year. Today I received an email announcing Camp Kahn which seems to be another way of approaching this by taking the "get ready" course for the grade your entering. So the question is whether taking the get ready course for the grade your entering test for any foundational gaps leading up to your grade? Remember, Sal Kahn said math is built on each previous lesson, thus the question.
Thanks for the feedback.
